I have two questions.
If I use mileage to upgrade from Y class to C class, will I get mileage from the flight? Will that be Y class mileage (100%) or C class mileage (150%). I know if you use mileage for an award flight you get nothing, but this is only an upgrade.
Another question is, suppose I have two star alliance member FF cards, TG and TK. If I use my TG mileage to upgrade my TG flight, will they allow me to claim the mileage onto my TK account?
Sorry if this is in the wrong forum, change this if necessary.
